Astronomers Find First Earth-like Planet in Habitable Zone

submitted by blanchette574
1 decade 7 years 7 months ago

Astronomers have discovered the most Earth-like planet outside our Solar System to date, an exoplanet with a radius only 50% larger than the Earth and capable of having liquid water. Using the ESO 3.6-m telescope, a team of Swiss, French and Portuguese scientists discovered a super-Earth about 5 times the mass of the Earth that orbits a red dwarf, already known to harbour a Neptune-mass planet. The astronomers have also strong evidence for the presence of a third planet with a mass about 8 Earth masses.

This has been in the news for a couple of days, so I suppose you already knew that. I thought it would be interesting to see the people behind this discovery.

That needed to be on the "Clouds and Beyond!" Collective. Nice sift.

Cool. I got my bags packed, when do we leave?

Right on! A Hockey planet! Seriously though these guys have the coolest job on Earth perhaps. I'd be happy to take my work home each night if I did this job. In the next ten years I'm sure we'll find a few "exactly" Earth like planets.

To an observer outside the solar system, earth's orbit would deflect the sun's motion by up to 0.09 m/s in either direction. To detect a Doppler shift that small would be difficult.

Holy Science-Fiction batman!

Weird alien creatures, Planet colonization, Space Age galactic warfare! YeeHAW!!!
